In Jainism, chovihar refers to the practice of refraining from eating or drinking anything after sunset until sunrise the next day. This is a key aspect of Jain ethical conduct, especially for lay followers (Śrāvakas and Śrāvikās) and is observed more strictly by monks and nuns.

Reason for Chovihar: The main reason for chovihar is to minimize violence (hiṃsā) toward living beings. After sunset, it becomes difficult to see small insects or microorganisms that might be present in food or water, increasing the risk of unintentionally consuming or harming them.

Sunset Timing: Traditionally, chovihar begins at or just before sunset (the exact time varies depending on local sunset timings). It is ideal to complete your meal and any drinking of water before sunset. The general guideline is to finish all eating and drinking activities at least a few minutes before the sun goes below the horizon.

Summary:

• Chovihar means no eating or drinking after sunset.
• All consumption must stop before sunset (ideally a few minutes prior).
• The practice is rooted in the Jain principle of non-violence (ahimsa).

If you want to observe chovihar, check your local sunset time daily and plan your last meal and drinks accordingly.
